Widespread occlusive vascular disease in a Crohn's disease patient with profound thrombocytosis.

A 47-year-old woman with Crohn’s disease developed severe arterial and venous thromboembolic events, including lower extremity ischemia, portal vein thrombosis, and cerebral infarct, alongside profound thrombocytosis (platelet count 1,237×10³/mm³). Bone marrow biopsy confirmed reactive thrombocytosis secondary to inflammatory bowel disease (IBD). Despite antiplatelet therapy and plateletpheresis, the patient required a transmetatarsal amputation and subtotal colectomy. While thromboembolic events occur in 1.2–6.7% of IBD patients, most are venous; arterial events are rare. Multiple risk factors were discussed, including elevated interleukin-6, thrombopoietin, antiphospholipid antibodies, and protein C resistance, though none singly predict events. IBD-induced inflammation triggers cytokines (IL-1, IL-6, TNF-α) that promote coagulation and inhibit fibrinolysis via various pathways, including increased platelet production and contact activation. The case highlights a rare combination of simultaneous arterial and venous thromboses in IBD, emphasizing the complex and multifactorial thrombotic risks in such patients and the need for careful risk assessment and individualized management.

Bilateral adrenal hemorrhage associated with heparin induced thrombocytopenia.

This case report describes a 54-year-old woman who developed bilateral adrenal hemorrhage (BAH) and acute adrenal insufficiency following heparin-induced thrombocytopenia (HIT) after receiving low molecular weight heparin (dalteparin) post-hip surgery. She presented with fever, severe abdominal pain, and a significant drop in platelet count, with imaging confirming BAH. Diagnostic workup revealed a positive heparin antibody panel, a femoral vein thrombosis, and a pulmonary embolism, confirming HIT. Immediate cessation of heparin products, administration of corticosteroids, fluid resuscitation, and initiation of direct thrombin inhibitor therapy with lepirudin led to rapid clinical improvement. The report emphasizes that adrenal hemorrhage due to HIT, although rare, can have fatal consequences if not promptly recognized and treated. Nonspecific symptoms such as abdominal pain, hyponatremia, and fever necessitate a high index of suspicion in patients on heparin presenting with new thrombocytopenia. The case underscores the importance of early HIT recognition, imaging, and appropriate anticoagulation and hormone replacement to avert life-threatening outcomes. This report contributes to the limited but critical documentation of adrenal complications arising from HIT.

Pyogenic liver abscess associated with a gastrointestinal stromal tumor of the stomach.

This case report details a rare presentation of a pyogenic liver abscess associated with a necrotic gastrointestinal stromal tumor (GIST) in a 65-year-old man. GISTs, mesenchymal tumors related to the interstitial cells of Cajal and characterized by c-kit mutations, commonly arise in the stomach. The patient presented with fatigue, fever, anemia, leukocytosis, and a palpable abdominal mass. Imaging revealed a large necrotic gastric mass and multiple hypodense liver lesions. Blood cultures grew Streptococcus species, and antibiotics were initiated. Endoscopy showed purulent discharge and a fistulous tract from the mass into the gastric lumen. Surgical exploration confirmed a CD117-positive spindle cell neoplasm (GIST) with liver abscesses; drainage yielded *Streptococcus intermedius*. Due to the patient’s critical condition, gastrectomy was deferred. After stabilization and resolution of sepsis, imatinib mesylate therapy began. The authors note that central necrosis and cavitation in large GISTs can lead to fistula formation and bacterial seeding of the liver, mimicking metastases. Only five similar cases have been reported. This case underscores the importance of considering liver abscesses in the differential diagnosis when necrotic gastric tumors are found, as radiologic findings may be misinterpreted as metastases.

Acute Diarrhea Caused by a Rectovesical Fistula After Laparoscopic Prostatectomy

A 62-year-old man developed acute diarrhea three weeks after undergoing robotic-assisted laparoscopic prostatectomy for prostate cancer. His postoperative course was complicated by a pelvic hematoma requiring arterial embolization and subsequent infection treated with antibiotics. He experienced frequent watery diarrhea with urgency and mild rectal bleeding. Initial stool studies were negative, including for *Clostridium difficile*. Flexible sigmoidoscopy revealed a fistulous tract from the rectum to a purulent cavity, later identified by contrast-enhanced CT as a rectovesical fistula. Diarrhea ceased after urinary catheter placement, and the patient underwent a diverting colostomy for fistula management. Rectovesical fistulas commonly present with pneumaturia or fecaluria, while diarrhea alone is rare. Causes include Crohn’s disease, diverticulitis, malignancies, and iatrogenic injuries, especially from prostate surgery. Rectal injury occurs in up to 11% of radical prostatectomies, with minimally invasive methods carrying risks. This case highlights an unusual sole presentation of diarrhea due to a rectovesical fistula resulting from unrecognized rectal injury and infected hematoma. Clinicians should consider this diagnosis in similar postoperative patients to ensure timely evaluation and intervention.
